Description
I've created this course to help you learn Node-RED and the Raspberry Pi Pico W. Whether you're an engineering educator, a student, an industrial automation professional, a research scientist, or an electronics hobbyist, these two technologies are essential.
Node-RED is an incredible open-source software development tool that allows you to create programs visually instead of writing them line by line.
The Raspberry Pi Pico W is a remarkable Wi-Fi microcontroller board for embedded projects. It offers high performance at a low cost.
This course teaches you how to set up a system that contains Node-RED and the Raspberry Pi Pico W .
You'll gain a solid understanding of Node-RED nodes, flows, and even MicroPython, enabling you to program the Pico W to interact with various peripherals. Additionally, this course covers essential topics such as MQTT, Ubuntu Linux virtual machines, Docker, and MySQL.
Designed specifically for beginners with a basic knowledge of electronics, this course will guide you step-by-step through everything you need to know.
Part 1: Node-RED for the absolute beginner
Part 1 is dedicated to Node-RED for the absolute beginner. In Part 1, you will learn about Node-RED and event-driven systems, how to install an instance using Docker, the basics of nodes and flows, the dashboard and MQTT.
Part 2: Add Raspberry Pi Pico W
In the lectures of Part 2, you will learn how to use the Pico W as a Node-RED peripheral. You will learn to use MQTT to enable communications between the Pico and the Node-RED instance. You will also learn how to connect different hardware components to the Pico to implement simple circuits and use Node-RED (and its Dashboard) to control these components or view the data they produce. In Part 2, you will encounter motion, distance and water level sensors, motors, displays, relays, and joysticks, to mention a few.
Part 3: additional Node-RED resources
These resources include lectures on essential Nodes, control structures, and ways to integrate your Node-RED flows with external services and APIs. You will create flows that allow Node-RED to communicate with services like OpenWeatherMap and Google Sheet to get, store, and retrieve data. You will also learn how to set up a local instance of the MySQL database for use by Node-RED for data storage and retrieval.
I highly recommend taking a few minutes to watch the "About this course" lecture for more detailed information.
I can't wait to have you join us on this exciting journey!
